I had this dream a couple of nights ago. Rudi was kidnapped by Robert Ford (from Westworld) who kept him in a secret laboratory in a basement of supermarket. Ford wanted to create a race of human-vampire hybrids and needed Rudi's blood, but Rudi wandered off to game aisle and Ford saw him no more. Lucifer/Ramsay Bolton wore stripy long socks and gloves but otherwise was naked.
